- the invention described in Claim 25 is the fundus observation apparatus of Claim 24, wherein after the still image and the information are displayed, the specifying part carries out image matching between a new frame of the fundus image acquired by the imaging part at the time of this display process and the single frame to specify an image region in the new frame corresponding to the image region specified in the single frame, and the controller controls the scanner based on the image region specified in the new frame to carry out the scanning of the signal light.

Further, the display position of the fixation target may be arbitrarily changed.
- the reflection surface of a reflection rod 67 is positioned at a slanted position on the optical path of the illumination optical system 10.
- Light (focus light) output from an LED 61 of the focus optical system 60 passes through a relay lens 62, is split into two light fluxes by a split target plate 63, passes through a two-hole diaphragm 64, is reflected by a mirror 65, and is reflected after an image is formed once on the reflection surface of the reflection rod 67 by a condenser lens 66.

- the optical path length changing part 41 is capable of moving in the direction indicated by the arrow in Fig. 1 to change the length of the optical path for OCT. This change of optical path length may be used for correction of the optical path length in accordance with the axial length of the eye E, and for adjustment of the condition of interference.

- the setting processor 2316 specifies a characteristic location (center, barycenter, site of characteristic form, etc.) of the lesion candidate site, and determines the location of a linear pattern such that it passes through this characteristic location specified. Further, when a pattern corresponding to a scanning pattern in which center position thereof exists (such as cruciform scan, radial scan, circular scan, concentric scan, helical scan) is selected, the setting processor 2316, for example, specifies a characteristic location of the lesion candidate site, and determines the location of the pattern such that the center position of the pattern is located at this characteristic location specified. Further, when three-dimensional scan is selected, it is possible to determine the location of the rectangular pattern such that the whole of the lesion candidate site is included in it.
